It features a 1-1\/4-7 UNC thread size and an 8-inch length under the head, making it well suited for thick-section joints and structural connections. The screw is driven with a 7\/8-inch hex key. Constructed from alloy steel with a black oxide coating, it delivers the hardness and shear strength required for demanding installations. Licensed trades and maintenance professionals working with heavy equipment, machinery, or structural assemblies will find this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial machinery assembly, heavy fabrication, and mechanical maintenance where a high-strength, large-diameter fastener is required. The 1-1\/4-7 UNC coarse thread engages well in steel and cast-iron tapped holes. The partial threading allows the unthreaded shank to act as a close-tolerance alignment feature in precision-bored holes. It is appropriate for both shop fabrication environments and field maintenance of large mechanical equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for reliable engagement in steel and cast-iron tapped bores\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head accommodates thick-section structural connections\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for close-tolerance alignment in precision holes\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex drive accepts standard hex keys and socket drive tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduced surface glare\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for industrial machinery, heavy fabrication, and mechanical assembly applications requiring a 1-1\/4-7 UNC partially threaded hex socket cap screw per ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of large-diameter socket cap screws typically requires a calibrated torque wrench and the correct 7\/8-inch hex key or drive socket to avoid cam-out and fastener damage. Always verify that the tapped hole is clean, free of debris, and threaded to the correct depth before installation. Follow applicable industry torque specifications for the joint material and fastener grade. Lubrication of threads may be required depending on the joint design and applicable engineering specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 011575BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697850646834,"sku":"011575BR","price":29.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_c2d659b6-fb52-473a-bec4-7197588da12f.jpg?v=1788354993","url":"https:\/\/voomisupply.com\/products\/value-collection-011575br-hex-socket-cap-screw-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
